Porohalacarus hydrachnoides ( Lohmann, 1893)

Syn.: Halacarus hydrachnoides Lohmann, 1893

Record from more than 900 m a.s.l. altitudes: France — Lakes of Estibèrc (Hautes-Pyrénées), between 2100 and 2300 m a.s.l. ( Angelier 1965).

Remarks: The specific nature of this species is doubtful. Lohmann (1893) poorly described this species as Halacarus hydrachnoides based on a juvenile. Bartsch (2009) commented that the description of this species was based on a juvenile and according to the description, its characters are intermediate between Porohalacarus alpinus alpinus and P. alpinus brachypeltatus , according to the collection data, it is most likely a synonym of P. alpinus . Angelier (1965) reported female of this species in mud bottoms of the Estibèrc lakes. Thus, specific nature of specimen from lakes of Estibèrc needs verification.
